<p>PURPOSE:To make it unnecessary to provide a space for fitting in a light source part on a cassette, and to make a titled device small-sized, by providing a light source part for detecting a tape end so as to be movable up and down, at a posi tion which is shifted slightly from a cassette installing part, and shunting the light source part at the time of loading. CONSTITUTION:A tape end detecting light source part 5 is provided so as to be movable up and down by a spring at a position of the inside slightly from a cassette installing part, on a supporting lever 30 whidh is supported axially by a pin 32 of a chassis 2, and is made to press-contact with an L-shaped lever 35 for controlling a motion of the lever 30. Before loading a tape, a lever 35 is detained to a pole supporting base 14, and the light source part 5 is in a position P1 of the lower part, but when the supporting base 14 is moved by loading, the lever 35 is turned, the light source part 5 also starts to rise, on which a tape 19 passes through and loading is executed, and after its completion, the light source part 5 takes a position P2 of the upper part, and detection of a tape end is executed. Therefore, it becomes unnecessary to provide a space for fitting in the light source part on a cassette, and a titled device can be made small-sized.</p> |
