2. Description of the Related Art FIG. 2 shows the structure of a conventional loading and ejecting device in a compact disc player. 1 is a compact disc (hereinafter referred to as "CD") on which audio information such as music is recorded, and 2 is a turntable. Three
The reproducing device 4, which reads out audio information from the CD 1 loaded in the CD 1, carries the CD 1 placed on the elevating table 5 in the left-right direction in the figure and moves up and down in the figure by the elevating table 5 to move the CD 1 to the CD 1. The tray 4 is a tray for loading or ejecting to the reproducing apparatus 2. The tray 4 is attached to a frame (not shown) of a CD player or the like so as to be movable in the left-right direction in the drawing. 6 is an arm projecting downward from the bottom surface of the tray 4 in the figure, 7 is a rack provided on the bottom surface of the tray 4 along the moving direction of the tray 4 (horizontal direction in the figure), 8 is a pinion 9 that meshes with the rack 7. Is a motor that is attached to the rotating shaft.

Reference numeral 10 denotes a loading eject switch (hereinafter referred to as "LE switch") which outputs a loading eject signal (hereinafter referred to as "LE signal") when the user presses a button. The LE switch 10 penetrates the case 11. It is equipped. 12 is a tray 4 that moves to the left in the figure
When the arm 6 of the touches the button, the tray detection signal E
The tray detection switch 13 on the eject side for outputting (hereinafter referred to as "detection signal E") is a tray detection signal L (hereinafter "detection signal It is a tray detection switch on the loading side that outputs "L").

In 14, the detection signal E is the tray detection switch 12
When the LE signal is input from the LE switch 10 while inputting from, the loading command signal (hereinafter referred to as “L command signal”) is output, and when the detection signal L is input from the tray detection switch 13, LE signal is LE switch
When input from 10, the eject command signal (hereinafter referred to as “E command signal”) is output, and when only the detection signal E is input from the tray detection switch 12 or only the detection signal L is input from the tray detection switch 13, the stop signal is output. Is a tray movement control unit for outputting.

When the L command signal is input from the tray movement control unit 14, the motor 15 rotates the motor 8 clockwise to load the tray 4 in the right direction in the drawing, and the E command signal the tray movement control unit. When input from 14, the motor 8 is rotated counterclockwise in the drawing to eject the tray 4 to the left in the drawing, and when a stop signal is input from the tray movement control unit 14, the rotation of the motor 8 is stopped and the tray is moved. 4 is a motor driving unit for stopping the movement of the motor.

The loading operation of the CD 1 in the conventional loading / ejecting apparatus thus constructed will be described.

When the tray 4 is in the eject position on the left side in the figure protruding from the front of the case 11, the arm 6 contacts the button of the tray detection switch 12, and the detection signal E is continuously output from the tray detection switch 12. There is. Therefore, when the user places the CD 1 on the lifting table 5 of the tray 4 and presses the button of the LE switch 10, an LE signal is output from the LE switch 10 and the tray movement control unit
The detection signals E and LE are input to 14, and the tray movement control unit 14 outputs an L command signal.

Then, the motor drive section 15 drives the motor 8 to rotate clockwise in the drawing at a constant speed based on the L command signal, thereby moving the tray 4 to the right in the drawing. For this reason, the arm 6 is separated from the button of the tray detection switch 12, and the detection signal E becomes the tray detection switch 12
However, the tray 4 continues to move rightward in the figure.

When the tray 4 reaches the loading position and the back surface 4a of the tray 4 contacts the button of the tray detection switch 13, the detection signal L is changed to the tray detection switch.
It is output from 13 and the detection signal L is sent to the tray movement control unit 14.
Since only the input is made, the tray movement control unit 14 outputs a stop signal. Then, the motor drive unit 15 stops the rotation of the motor 8 and the movement of the tray 4 based on the stop signal. Therefore, the contact state between the back surface 4a of the tray 4 and the button of the tray detection switch 13 is maintained, and the detection signal L is continuously output from the tray detection switch 13.

After this, the elevating table 5 descends and the CD
When 1 is transferred from the lift table 5 to the turntable 3, the audio information can be read from the CD 1.

Next, the eject operation of the CD 1 will be described.

When the tray 4 is stored in the case 11 at the loading position on the right side in the drawing, the back surface 4a of the tray 4 contacts the button of the tray detection switch 13, and the detection signal L is output from the tray detection switch 13. It continues to be output. Therefore, when the user presses the button of the LE switch 10, the LE signal is output from the LE switch 10, and the detection signals L and LE are input to the tray movement control unit 14,
The tray movement controller 14 outputs an E command signal.

Then, the elevating table 5 rises, and the CD
After 1 is transferred from the turntable 3 to the lifting table 5, the motor drive unit 15 drives the motor 8 to rotate counterclockwise in the drawing at a constant speed based on the E command signal, thereby causing the tray 4 to move. To the left in the figure. Therefore, the back surface 4a of the tray 4 is separated from the tray detection switch 13 and the detection signal L is not output from the tray detection switch 13, but the tray 4 continues to move leftward in the figure.

When the tray 4 reaches the eject position and the arm 6 comes into contact with the button of the tray detection switch 12, a detection signal E is output from the tray detection switch 12 and the tray movement control unit 14 detects the detection. Since only the signal E is input, the tray movement control unit 14 outputs a stop signal. Then, the motor drive unit 15 stops the rotation of the motor 8 and the movement of the tray 4 on the basis of the stop signal so that the CD 1 can be taken out or replaced from the tray 4. At this time, the arm 6 and the tray detection switch
The contact state with the button 12 is maintained, and the detection signal E is continuously output from the tray detection switch 12.

After that, every time the user presses the button of the LE switch 10 in this way, the tray 4 is alternately moved to the loading position and to the eject position to load or load the CD 1. The eject is performed.

[0016]

By the way, in such a conventional loading and ejecting apparatus, the moving speed of the tray 4 at the time of loading or ejecting a portable recording medium such as the CD 1 is set to be constant. For this reason, if the time required for loading or ejecting does not match the feeling of the user at that time, that is, if the user feels that the time is short, the luxury feeling is not felt, and conversely, if the time is long, it is frustrating. There was a problem that we would be recruiting.

[0017]

In order to solve such a problem, the present invention proposes a pressure detecting means for detecting pressure and time when a button is pressed, and a pressure detecting means for pressing a button of an LE switch. Speed adjusting means for adjusting the moving speed of the tray according to the pressure and time.

According to the present invention, when it is detected by the pressure detecting means provided in the LE switch that the button of the LE switch is pressed with a strong force for a short time, the moving speed of the tray is increased to perform loading or ejecting. When it is detected that the LE switch button has been pressed with a weak force for a long time, the moving speed of the tray is slowed down to lengthen the time required for loading or ejecting, thereby increasing the time required for loading or ejecting. The time required to match the feeling of the user at that time.

[0019]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which the same reference numerals as those in FIG. 2 indicate the same parts, and 16 indicates the loading when the user presses a button. -Loading eject switch (hereinafter referred to as "LE") that outputs an eject signal (hereinafter referred to as "LE signal")
This LE switch 16 is case 11
Has been penetrated. Reference numeral 17 is a pressure detector that outputs a pressure signal corresponding to the pressure and time when the button of the LE switch 16 is pressed. The pressure detector 17 is provided integrally with the LE switch 16.

In 18, the detection signal E is the tray detection switch 12
When the LE signal is input from the LE switch 16 while inputting from, the loading command signal (hereinafter referred to as “L command signal”) is output, and when the detection signal L is input from the tray detection switch 13, LE signal is LE switch
When input from 16, an eject command signal (hereinafter referred to as “E command signal”) is output, and when only the detection signal E is input from the tray detection switch 12 or only the detection signal L is input from the tray detection switch 13, a stop signal is output. Is a tray movement control unit for outputting.

When a pressure signal is input from the pressure detector 17, 19 outputs a speed instruction signal corresponding to the pressure and time information of the pressure signal. For example, the button of the LE switch 16 is pressed with a strong force for a short time. The speed adjusting unit outputs a high speed speed instruction signal, and outputs a low speed speed instruction signal when the button of the LE switch 16 is pressed with a weak force for a long time.

Reference numeral 20 is an L input from the tray movement control unit 14.
The motor 8 is rotated in the clockwise direction in the drawing in response to the command signal at a speed in accordance with the speed instruction signal input from the speed adjusting unit 19, so that the tray 4 is loaded and moved rightward in the drawing, and the tray movement control unit 14 is operated. The motor 8 is rotated counterclockwise in the drawing in response to the E command signal input from the motor 8 at a speed corresponding to the speed instruction signal input from the speed adjusting unit 19 to eject the tray 4 leftward in the drawing. When the stop signal is input from the tray movement control unit 14, the rotation of the motor 8 is stopped,
This is a motor drive unit that stops the movement of the tray 4.

The loading operation of the CD 1 in the loading / ejecting apparatus of the present invention thus constructed will be described.

When the tray 4 is in the eject position on the left side in the figure protruding from the front of the case 11, the arm 6 contacts the button of the tray detection switch 12, and the detection signal E is continuously output from the tray detection switch 12. There is. Therefore, when the user mounts the CD 1 on the lifting table 5 of the tray 4 and presses the button of the LE switch 16, the LE signal is output from the LE switch 16 and the tray movement control unit.
Since the detection signals E and LE signals are input to the 18, the tray movement control unit 18 outputs the L command signal, and at the same time, the pressure signal corresponding to the pressing pressure of the button of the LE switch 16 and the time is sent from the pressure detector 17 to the speed detector 17. In order to input to the adjusting unit 19, the speed adjusting unit 19 outputs a speed instruction signal according to the pressure and time information of the pressure signal.

Then, the motor drive unit 20 drives the motor 8 to L
Based on the command signal, clockwise in the figure, the speed instructed by the speed instruction signal, for example, if the button of the LE switch 16 is pressed with a strong force for a short time, the speed is high, and the button of the LE switch 16 is a weak force. If the tray 4 is pressed for a long time, it is rotated at a low speed to move the tray 4 rightward in the drawing. Therefore, the arm 6 moves to the tray detection switch 12
Although the detection signal E is no longer output from the tray detection switch 12 after being separated from the button, the tray 4 continues to move rightward in the figure.

When the tray 4 reaches the loading position and the back surface 4a of the tray 4 contacts the button of the tray detection switch 13, the detection signal L changes to the tray detection switch.
It is output from 13 and the detection signal L is sent to the tray movement control unit 18.
The tray movement control unit 18 outputs a stop signal because only the input is made. Then, the motor drive unit 20 stops the rotation of the motor 8 and the movement of the tray 4 based on the stop signal. Therefore, the contact state between the back surface 4a of the tray 4 and the button of the tray detection switch 13 is maintained, and the detection signal L is continuously output from the tray detection switch 13.

Thereafter, the elevating table 5 descends and the CD
When 1 is transferred from the lift table 5 to the turntable 3, the audio information can be read from the CD 1.

Next, the eject operation of the CD 1 will be described.

When the tray 4 is stored in the case 11 at the loading position on the right side in the drawing, the back surface 4a of the tray 4 contacts the button of the tray detection switch 13, and the detection signal L is output from the tray detection switch 13. It continues to be output. Therefore, when the user presses the button of the LE switch 16, the LE signal is output from the LE switch 16 and the detection signals L and LE are input to the tray movement control unit 14, so that the tray movement control unit 18 outputs E. At the same time that the command signal is output, the pressure signal corresponding to the pressing pressure of the button of the LE switch 16 and the time is input from the pressure detector 17 to the speed adjusting unit 19. The corresponding speed instruction signal is output.

Then, the elevating table 5 rises, and the CD
After 1 is transferred from the turntable 3 to the lift table 5, the motor drive unit 20 moves the motor 8 counterclockwise in the figure based on the E command signal to the speed designated by the speed designation signal, for example, LE. When the button of the switch 16 is pressed with a strong force for a short time at high speed, and when the button of the LE switch 16 is pressed with a weak force for a long time, at low speed, the tray 4 is rotated leftward in the figure. To move.
For this reason, the back surface 4a of the tray 4 has the tray detection switch 13
Although the detection signal L is no longer output from the tray detection switch 13 away from, the tray 4 continues to move leftward in the figure.

When the tray 4 reaches the eject position and the arm 6 comes into contact with the button of the tray detection switch 12, a detection signal E is output from the tray detection switch 12 and the tray movement control unit 18 detects the detection signal E. Since only the signal E is input, the tray movement control unit 18 outputs a stop signal. Then, the motor drive unit 20 stops the rotation of the motor 8 and the movement of the tray 4 based on the stop signal, so that the CD 1 can be taken out or replaced from the tray 4. At this time, the arm 6 and the tray detection switch
The contact state with the button 12 is maintained, and the detection signal E is continuously output from the tray detection switch 12.
