In unloading the cassette, an ejection switch 7 is operated and the cassette is taken out from the loading position and during intervals from the time when the switch 12 is turned off to the time when the switch 10 turns off, the light emitting diode train illuminates from the center C to the outside direction.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording/reproducing apparatus equipped with a cassette loading device, and in particular, an object of the present invention is to provide a novel magnetic recording/reproducing apparatus that can display the loading status.

Conventionally, by using the torque of a motor, the cassette inserted through the cassette insertion window is automatically installed at a predetermined position where the tape will run, and vice versa. Cassette loading devices that automatically eject cassettes are known. There are magnetic recording and reproducing devices that incorporate this cassette loading device, but
There were no indications that the cassette was automatically installed or removed.

The present invention provides a magnetic recording/reproducing device that can display the operating status of a cassette loading device using a plurality of display element rows, and is capable of accurately informing the user of the moving status of a cassette. It is. An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a front view showing the appearance of an embodiment of the magnetic recording/reproducing apparatus of the present invention. 1 is the main body of the device, 2 is a cassette insertion window, 3 to 7 are switches of the operation section, 3 is a fast forward switch, 4 is a stop switch, 6 is a rewind switch, 6 is a travel reversal switch, and 7 is an eject switch. It is. Reference numeral 8 denotes a display section in which five light emitting diotoms, B, C, D, and IC are arranged in a row. FIG. 2 shows the main circuitry of this embodiment. Reference numeral 9 denotes a control unit including a microcomputer, and this figure only shows the input/output connections for Ω regarding the cassette loading function and its display. Output terminal 91L of control unit 9.

sb, 90.9d, and 9e are each shown above.

One ends of the light emitting diotoms B, C, D, and E are connected. The other ends of the light emitting diodes A to E are connected in common and connected to a power source 11 via a switch 1o. Note that the switch 1o is the power input terminal 9f of the control section.
is also connected. This switch 10 is a switch that is turned on when the cassette is inserted and held in the cassette insertion window 2 and is pushed further inward from this position. In this embodiment, the control section 9 starts controlling the display section, which will be described later. At the same time, it instructs the cassette loading mechanism to start the loading operation. Reference numeral 12 denotes a switch that is turned on when the cassette is correctly installed in a position where the tape can run, and is connected to the input terminal 9g of the control section 9. Note that each of the switches f3 to f7 of the operation section is an input terminal 9h of the control section 9.

It is connected to 9i, 9j, 9, and 91.

Next, the operation of this embodiment will be explained with reference to FIGS. 3, 4, and 6. FIG. This section shows all the parts related to the display when loading a cassette. Figures 4 and 6 show the display when the display is turned on.
``2 lights are shown in white, and lights out are shown in black, and the vertical axis shows the state of each time as time passes from top to bottom. Note that FIG. 4 shows the display state during the loading operation of one cassette, and FIG. 6 shows the display state during the ejection operation of the cassette.

First, a cassette is inserted into the cassette insertion window 2, and when this cassette is further inserted lightly to the back and the switch 10 is turned on, the program execution starts from 3 in FIG.

Variable X is light emitting diode A~! The light emitting diodes A to F are kept lit until K=&. If the switch 12 is not turned on until =a, the program executes a loop of ■-■-0.

Next, when IC=a, the process proceeds to ■, but since H=6 initially, the process proceeds to ■. At this point, all of the light emitting diodes 5 to X are turned off. Furthermore, to reach ■, execute =o, H=R+1, and return to ■. Therefore, all the light emitting diodes are off until the next time X=a.

If it becomes = & again, it is Sea 1, so it proceeds and lights up the light emitting diode 1 IC. Then, in the same manner as above, execute =o, H=H+1, and return to step (2).

Here's a light emitting diode! 0 continues to be lit. When IC=a again, this time H=2, so the process proceeds to ■, and light emitting diodes B and D are lit.

In this way, it is the duration of the time when =a (the counting period is one lighting state (sometimes the lighting is off)).

In the same way as above, in the next = a) Since I = 3, ■
The light emitting diode C lights up. Also, at H = 3, ■
So next time! (Repeat the above operation from =O.
vinegar.

To illustrate this, as shown in Fig. 4, from the time ta when the cassette is inserted and the switch 1o is turned on, to the time t and b when the cassette is installed in the normal position and the switch 12 is turned on, the above-mentioned By repeatedly executing the program, the lighting position moves toward the outside or inside.
' 1. When ejecting a cassette, operate the eject switch 7 to remove the cassette from the mounting position, and switch 12 is turned off at point 1 (), when the cassette reaches the cassette insertion window and switch 1o is turned off. Until time t6, one light emitting diode row is moved from center C to B.
, D, and then lights up moving from the inside to the outside like M and E.

This operation can be realized in exactly the same way by changing the program shown in the flowchart shown in FIG. 3 to one in which the variable H is decreased over time, and by changing the selection of the light emitting diodes to be driven.

According to the above embodiment, the switch 12 is turned on after the cassette is inserted and the switch 1o is turned on.

Until the kite is turned on, the light emitting diodes in the display section 8 will light up sequentially from the outer side to the inner side, so the light will appear to flow from the outside to the inside of the kite, and the cassette loading operation will be activated. On the other hand, between the time when the eject switch is operated and the switch 12 is turned off, and the time when the switch 10 in the cassette insertion window is turned off, the light emitting diode in the i display section Since the lights are lit sequentially from the inside to the outside, the light appears to flow from the inside to both sides, making it easy to see that the cassette is being ejected.In this way, the cassette-loading device is The operating state can be easily determined.The display section 8 may be particularly large with a cassette rope.
It may also be used as a display section that displays the running direction of the tape by moving the lighting position or a display section that displays the level of output, and these display function tools 710.12 may be mechanical micro-items. , an optical switch that combines a light emitting element and a light receiving element may be used. .

As described above, in the present invention, the operating status of the cassette loading device is indicated by the display elements arranged in a row, that is, during the operation of loading the cassette, the display elements 5 from the outer display element to the inner display element 5 are sequentially turned on.1. During the operation of ejecting the cassette, the display elements from the inner display element to the outer display element are turned on sequentially, so that the user can immediately determine the operating state.゛
