[Problems to be Solved by the Invention] However, the aforementioned mounting device for the previous disc cartridge has the following problems. (1) When the disc cartridge is inserted into the main body of the device, the locking convex part is subjected to the elastic pressure from the elastic member, while being pressed against the side wall of the guide groove formed on the disc cartridge while sliding, causing insertion of the disc cartridge The load becomes heavier. In particular, when the disc cartridge is inserted into the insertion opening of the device body, since the resilient locking convex portion must be forced to intervene in the guide groove, the resistance at the beginning of insertion is increased. (2) When the locking protrusion is located in the locking groove of the disc case, the locking protrusion cannot be used as the disc case when the locking protrusion is pressed against the wall of the guide groove. Guide member to use. Therefore, it is necessary to provide more guide protrusions other than the locking protrusions in the box mounting area of the device body, so that the constituent parts of the box mounting portion are increased, and the component arrangement density of the box mounting portion Becomes high. (3) The detection switch is activated by the locking member, and the detection switch is not limited to mounting the disc case in the case mounting area, and the detection switch is switched only when the locking protrusion is engaged with the locking groove. When the disc cartridge is taken out, turning the locking member also causes the detection switch to switch. That is, the state of the detection switch is the same when the disc cartridge is loaded and when it is removed. As a result, after the power is turned on, it is impossible to identify whether the disc E body is loaded or has been removed. The above problem is not only for the disc box, but also for the thick paper and wood in the scales other than the disc.

Set time in the description of the invention (16), for example, the switch detects the protrusion of the disc cartridge P In the position shown in Figure 4, when the detection output is obtained, the motor will be operated. 'Move lever 2 5 to X 1 side]], or move lever 2 5 from ① position to ② position. The locking member 11 is actuated, and after the disc cartridge P is unlocked, a predetermined time is set by a timer, and after this predetermined time, the lever 2 5 can be restored to the direction of X1. As shown in FIG. 6 (A) It is shown that when the disc cartridge P is installed, after the lock is released, in order to enable the stop arm 3 3 to be inserted into the stop groove 1 d immediately, the end portion 1 d 2 of the stop groove 1 d is located The tip is located on the X 2 side more than the stopper protrusion 3 3 a. The disc tray P is ejected by the ejection plate 1 4. When the ejection plate 1 4 stops at the (spoon) position, the stopper is stopped. The end 1 d 1 of the groove 1 d must be blocked by the stopper protrusion 3 3 a or must be very close. Therefore, the length L of the stopper groove 1 d is the moving distance of the ejection plate 14, that is, it must be with the disc magazine. Body P from The moving distance from the locked state until the ejection plate 1 4 is pushed out is equal to or greater than this distance.

In this embodiment, as shown in FIG. 5, only when the disc cartridge P is locked in the mounting area B, the lock member 11 is turned to the α 1 direction, and the detection switch SW is ON, and In other states, that is, when the disc cartridge P is not inserted and in the middle of insertion, the locking member 11 is rotated in the direction of α2 by the restriction of the restriction link 18, and the detection switch SW ν is always 0. FF. In this way, the detection switch SW is ON only when the disc cartridge P is loaded, so whether or not the disc cartridge P is loaded can be reliably detected by one detection switch SW.
