Yes. As shown in FIG. 2, inside the apparatus main body 2, there are a photosensitive drum 12 as an image carrier, a charger 13 for uniformly charging the surface of the photosensitive drum 12, and a charged photosensitive drum. 12 is irradiated with light corresponding to image information to form an electrostatic latent image on the photosensitive drum 12, an optical scanning device 14 such as a laser scanner unit (LSU), and the photosensitive drum 12 using toner as a developer. A developing device 15 that develops the electrostatic latent image on the image to make it visible, a transfer device 16 that transfers the toner image on the photosensitive drum 12 onto the paper supplied from the paper feed cassettes 7 and 8, and a transfer Various process devices such as a fixing device 17 for fixing the toner image on the sheet are accommodated. Then, the paper on which an image is formed through a series of electrophotographic processes is discharged to the paper discharge tray 5.

又、装置本体2の右側部には上下方向に延びる搬送パスSが形成されており、搬送パスSの右横には、用紙の両面に画像を形成する場合に使用される別の搬送パスS’が略平行に形成されている。そして、更にその右の装置本体2の外側の側面にはバイパス給紙部18が設けられている。バイパス給紙部18には給紙トレイ18aが設けられており、該給紙トレイ18aは非使用時には装置本体2の右側面に沿って収納可能になっている。   Further, a conveyance path S extending in the vertical direction is formed on the right side of the apparatus main body 2, and another conveyance path S used when images are formed on both sides of the sheet is located on the right side of the conveyance path S. 'Is formed almost parallel. Further, a bypass paper feeding unit 18 is provided on the outer side surface of the right apparatus body 2. The bypass paper supply unit 18 is provided with a paper supply tray 18a that can be stored along the right side surface of the apparatus main body 2 when not in use.

ところで、装置本体2の矩形ボックス状の筐体9の側面下部には、図3〜図5に示すように、給紙カセット7,8に隣接する段凹部9Aが形成されており、その上方の搬送パスS、S´及び給紙トレイ18aを収納する部分は段凹部9Aに対して外側方に張り出す段凸部9Bを構成している。従って、筐体9の側面の段凹部9Aと段凸部9Bの境界には前後方向に沿う稜線9aが存在し、この稜線9aに沿う奥側の段凸部9Bには、図4に示すように矩形の凹部9bが形成されており、この凹部9b内に電源スイッチ10が配置されている。尚、電源スイッチ10は、装置本体2への電源の供給をON/OFFする機能を果たすものである。   By the way, as shown in FIGS. 3 to 5, a step recess 9 </ b> A adjacent to the paper feed cassettes 7 and 8 is formed at the lower side of the rectangular box-shaped housing 9 of the apparatus body 2. A portion that accommodates the conveyance paths S and S ′ and the paper feed tray 18a constitutes a stepped protrusion 9B that projects outward from the stepped recess 9A. Therefore, a ridge line 9a along the front-rear direction exists at the boundary between the step recess 9A and the step protrusion 9B on the side surface of the housing 9, and the step protrusion 9B on the inner side along the ridge line 9a has a ridge line 9a as shown in FIG. A rectangular concave portion 9b is formed in the concave portion 9b, and the power switch 10 is disposed in the concave portion 9b. The power switch 10 functions to turn on / off the power supply to the apparatus main body 2.

筐体9の段凸部9Bに形成された凹部9bの側方に開口する開口部は、上端を中心として回動するスイッチ保護カバー11によって開閉されるが、電源スイッチ10を操作しないときにはスイッチ保護カバー11は図3に示すように閉じられて電源スイッチ10を覆ってこれを保護している。そして、電源スイッチ10を操作するときには、図4に示すようにスイッチ保護カバー11を上端を中心として回動させてこれを開き、筐体9の凹部9bに露出する電源スイッチ10を操作することができる。   The opening that opens to the side of the concave portion 9b formed in the stepped convex portion 9B of the housing 9 is opened and closed by a switch protective cover 11 that rotates about the upper end. However, when the power switch 10 is not operated, the switch protection is provided. As shown in FIG. 3, the cover 11 is closed to cover the power switch 10 to protect it. When operating the power switch 10, as shown in FIG. 4, the switch protection cover 11 is rotated around the upper end to open it, and the power switch 10 exposed in the recess 9 b of the housing 9 can be operated. it can.

而して、本実施の形態に係る画像形成装置1においては、電源スイッチ10を筐体9の側面に形成された段凹部9Bと段凸部9Bとの境界である稜線9aに沿う位置に配置したため、弱視者であっても或いは暗い室内であっても、筐体9の稜線9aに沿って手を移動させれば、この稜線9aがガイドとなって電源スイッチ10へとオペレータの手が誘導されるため、この電源スイッチ10の位置を手探りによって容易に探し出し、図4に示すようにスイッチ保護カバー11を開いて電源スイッチ10を容易且つ確実に操作(ON/OFF)することができる。   Thus, in the image forming apparatus 1 according to the present embodiment, the power switch 10 is disposed at a position along the ridge line 9a that is a boundary between the stepped recess 9B and the stepped protrusion 9B formed on the side surface of the housing 9. Therefore, even if it is a low vision person or a dark room, if the hand is moved along the ridge line 9a of the housing 9, the ridge line 9a serves as a guide to guide the operator's hand to the power switch 10. Therefore, the position of the power switch 10 can be easily found by searching, and the switch protection cover 11 can be opened and the power switch 10 can be easily and reliably operated (ON / OFF) as shown in FIG.

次に、本発明の別実施形態2を図5及び図6に基づいて説明する。
図5は本発明の別実施形態に係る画像形成装置の電源スイッチ部分を斜め下方から見た部分斜視図、図6(a)は同画像形成装置の電源スイッチ部の断面図、図6(b)は同スイッチ部の変形例を示す断面図である。
図5及び図6(a)に示すように、本実施の形態では、電源スイッチ10は段凹部9Aと段凸部9Bの間で下方に面している段差面9C上に設けられている。従って、前記実施形態と同様に筐体9の稜線9aに沿って手を移動させれば、電源スイッチ10を容易且つ確実に操作(ON/OFF)することができる。又、段差面9Aは下方に面しているため、通常の操作において触れることはなく、保護カバー等は不要である。
Next, another embodiment 2 of the present invention will be described with reference to FIGS.
FIG. 5 is a partial perspective view of a power switch portion of an image forming apparatus according to another embodiment of the present invention viewed obliquely from below, FIG. 6A is a cross-sectional view of the power switch portion of the image forming apparatus, and FIG. ) Is a cross-sectional view showing a modification of the switch portion.
As shown in FIGS. 5 and 6A, in the present embodiment, the power switch 10 is provided on a step surface 9C facing downward between the step recess 9A and the step protrusion 9B. Therefore, if the hand is moved along the ridge line 9a of the housing 9 as in the above embodiment, the power switch 10 can be easily and reliably operated (ON / OFF). Further, since the step surface 9A faces downward, it is not touched during normal operation, and a protective cover or the like is unnecessary.

又、図6(b)に示す例では、段差面9Cは、段凹部9Aから傾斜して上方に延びて段凸部9Bに繋がっている。電源スイッチ10は傾斜した段差面9Aに沿って配置されている。従って、筐体9の稜線9aに沿って手を移動させれば、電源スイッチ10を容易且つ確実に操作(ON/OFF)することができる。又、段差面9Aは下方に傾斜しているため、通常の操作において電源スイッチ10に触れる危険性は低いとともに、電源スイッチ10の状態を使用者が確認することも容易である。   In the example shown in FIG. 6B, the step surface 9C is inclined from the step recess 9A and extends upward to be connected to the step protrusion 9B. The power switch 10 is disposed along the inclined step surface 9A. Therefore, if the hand is moved along the ridge line 9a of the housing 9, the power switch 10 can be easily and reliably operated (ON / OFF). Further, since the step surface 9A is inclined downward, the risk of touching the power switch 10 during normal operation is low, and the user can easily confirm the state of the power switch 10.

尚、以上は本発明を複合機に対して適用した形態について説明したが、本発明は、複写機やプリンタ等の他の任意の画像形成装置に対しても同様に適用可能であることは勿論である。   Although the present invention has been described with respect to an embodiment in which the present invention is applied to a multifunction peripheral, the present invention can be similarly applied to any other image forming apparatus such as a copying machine or a printer.
