Abstract

PURPOSE:To prevent an insertion error and a malfunction, by detecting a recessed part of the screw hole for assembling of a cassette half, and detecting an inserting direction of the cassette half. CONSTITUTION:A microswitch 3 is fixed to a recorder body so that a plunger 4 contacts with a position of an assembling screw hole 2 of a cassette half 5. When the cassette half 5 is inserted upwardly, the plunger is depressed into the screw hole 2 by spring force of the microswitch 3, and a contact of the microswitch 3 is turned off. On the contrary, when the cassette half 5 is inserted downwardly, the contact is turned on since there is no screw hole 2. In this way, the inserting direction of the cassette half 5 can be detected by whether the microswitch 3 is on or off.

Description

【発明の詳細な説明】 この発明はカセットハーフの挿入向きを検出することが
でへるカセットテープレコーダに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette tape recorder capable of detecting the insertion direction of a cassette half.

従来のカセットテープレコーダはカセットハーフがいず
れの向きに挿入されたかを検知することができず、里っ
て逆面の捷ま操作するという欠点があった。Conventional cassette tape recorders have the disadvantage of not being able to detect which direction the cassette half is inserted, and having to flip the cassette half from one side to the other.

Except for 2), they have the same structure, and there is a screw hole (
There is no 21. Therefore, when the cassette half (5) is inserted, if it is detected whether there are four screw holes at the position of the screw hole (2), the cassette half (6) is inserted upward or downward. It is possible to detect
