に長期間の使用による機械的疲労などの問題がある。In such a conventional optical communication apparatus, every time the arrangement of an apparatus such as an image forming apparatus for performing optical communication is changed, an attempt is made to perform optical communication with a new apparatus. Each time, the communication direction is adjusted. However, in the communication unit disclosed in Japanese Patent Application Laid-Open No. 9-244774, the operation is time-consuming because the direction is adjusted by groping, and the positioning accuracy is low. In the infrared communication device disclosed in Japanese Patent Application Laid-Open No. 9-307502, the position of the partner communication device can be detected only in a limited horizontal direction. In the case where the communication device is fixedly mounted on the device, there is an inconvenience that, in order to detect a partner communication device located behind the device, it is necessary to perform an operation of changing the direction of the device to the rear and keeping it within a detectable range. As described above, the use of the conventional optical communication device causes a reduction in the efficiency of the setting operation. In addition, since the adjustment of the communication direction is performed mechanically, the device configuration tends to be complicated, and there are problems such as mechanical fatigue due to long-term use.

As shown in FIG. 9A, since the light receiving element 54 of the second light receiving unit 43 is provided on a frusto-conical surface, all the light receiving elements 54 should be orthogonal to the received infrared light.

ができる。Now, consider two light receiving elements 54R, 54L arranged symmetrically. The light receiving surface of the light receiving element 54R is inclined from the orthogonal plane by an angle of -θ1,
Assuming that the light receiving surface of L is inclined from the orthogonal plane by an angle of -θ2 (0 ° <θ1, θ2 <90 °), the light receiving intensity of the light receiving element 54R and the light receiving element 54L are equal and the intensity is the same. When the second light receiving unit 43 is moved so that is the largest, the central axis of the transmitted infrared ray coincides with the central axis of the mounting cone 53, and the maximum light receiving position is reached. In this case, of course θ1
= Θ2, but in the fine adjustment process immediately before the adjustment is completed, θ
When 1 ≠ θ2, the light receiving intensities per unit area of the light receiving elements 54R and 54L are approximately Pcos θ1 and Pcos, respectively.
Since sθ2 (P is the received light intensity per unit area in the orthogonal plane), the difference in the amount of received light between the two can be emphasized. Therefore, the last fine adjustment can be performed accurately.
The same principle applies to the first light receiving unit 42. Further, in the present embodiment, the surface on which the light receiving element is mounted is inclined rearward from the plane orthogonal to the infrared transmission direction. However, the present invention is not limited to this, and as shown in FIG. You may. In this case, the same effect can be obtained.
