[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a recording medium reproducing apparatus according to the present invention will be described with reference to the drawings. The drawings schematically show only parts required for the description of the present invention. FIG. 1 is a partial perspective view, in which (A) shows a state in a non-adjustment position and (B) shows a state in an adjustment position. 2A and 2B are partial cross-sectional views, wherein FIG. 2A shows a state at a non-adjustment position, and FIG. 2B shows a state at an adjustment position.
[0007]
In the drawing, reference numeral 1 denotes a main body of a recording medium reproducing apparatus, which has a built-in recording medium (for example, MD (mini-disc)) reproducing section 2 and has a panel mechanism 3 on its front surface. The panel mechanism 3 includes a front panel 4 having a display unit 4a and the like, and a recording medium insertion unit 5.
[0008]
The front panel 4 has an elongated hole 7a provided on both sides of a sub-panel 6 fixed to the apparatus main body 1, and support shafts 4b (not shown) provided at both ends on the upper side. A non-adjustment position P1 (position shown in FIG. 1A and FIG. 2A) that is parallel or almost parallel to an adjustment position P2 (FIG. 1B And a position shown in FIG. 2B), and two L-shaped movements which are moved inward and outward inside both side surfaces of the apparatus main body 1 by driving means (not shown) such as a motor. The member 8 is rotatably supported.
[0009]
The recording medium insertion portion 5 is connected to the front panel 4 by a hinge (not shown) at a position below the front panel 4 and is fixed to the L-shaped moving member 8, so that the front panel 4 is at the non-adjustment position P1. When the front panel 4 is at the adjustment position P2, the front panel 4 is arranged so as to be separated from the apparatus main body 1 and horizontally project forward.
The recording medium insertion section 5 is provided with an insertion port 5a and operation keys 10. A recording medium detection sensor (for example, a photo sensor) 9 for detecting that the MD disk 11 has been inserted into the insertion port 5a is provided. It is attached to an appropriate position (for example, an upper portion and a lower portion in the insertion slot 5a).
[0010]
When the operation key 10 is operated, a command signal for commanding an operation function of the apparatus is supplied to a microcomputer (not shown, but hereinafter referred to as a microcomputer) for controlling the entire operation of the apparatus. Is controlled.
[0011]
In the above-described structure, the panel mechanism 3 is moved to the non-adjustment position (see FIG. 1A) by operating the operation key 10 on the front panel 4 (or another position) and moving the L-shaped moving member 8 by the driving means. The front panel 4 can be moved from the close position P1 to the adjustment position (open position) P2 shown in FIG. 1B or vice versa from the adjustment position (open position) P2 to the non-adjustment position (close position) P1. Can be adjusted to a position where the display unit 4a can be easily viewed or a position where the operation keys 10 can be easily operated.
[0012]
Therefore, when the panel mechanism 3 is at the non-adjustment position P1 as shown in FIG. 2A, the MD disc 11 is inserted into the insertion slot 5a, and the MD disc 11 is inserted into the recording medium reproducing unit 2 from the insertion slot 5a. Can be loaded (withdrawn).
[0013]
Next, as shown in FIG. 2B, when the MD mechanism 11 is inserted into the insertion slot 5a when the panel mechanism 3 is at the adjustment position P2 and the panel angle is adjusted, the recording medium detection sensor 9 is turned on ( When the disk is inserted (passed), the light is shut off and the presence of the disk is detected), and a detection signal is supplied to the microcomputer. The microcomputer determines that the detection signal is supplied and the panel mechanism 3 is at the adjustment position P2. Then, driving means such as a motor is activated, the L-shaped moving member 8 moves in the direction toward the inside of the main body, the panel mechanism 3 performs a closing operation, and returns to the non-adjustment position P1 shown in FIG.
Therefore, the MD disk 11 can be loaded (pulled) into the recording medium reproducing unit 2 from the insertion slot 5a. At this time, the MD disk 11 may be inserted by hand to the end following the closing operation of the panel mechanism 3, or may be configured to be automatically retracted by the transport means when inserted partially.
[0014]
When the microcomputer recognizes that a certain period of time has passed after the closing operation of the panel mechanism 3, the microcomputer again activates driving means such as a motor, and the L-shaped moving member 8 moves toward the inside of the main body to move the panel mechanism 3 to the non-adjustment position. Returning from P1 to the last adjustment position of the adjustment position P2 (that is, the original adjustment position shown in FIG. 2B), the angle of the front panel 4 is adjusted, and the display unit 4a is easily viewed or the operation keys 10 are easily operated. It can be returned to the position.
[0015]
Next, the above operation will be described with reference to the flowchart shown in FIG.
First, in step S1, the microcomputer determines whether or not the recording medium detection sensor 9 is ON. If YES, the process proceeds to S2, where the microcomputer determines whether or not the panel mechanism 3 is at the adjustment position P2. The microcomputer performs close control of the panel mechanism 3.
Next, in S4, the microcomputer determines whether or not the panel mechanism 3 has reached the close position P1, and if yes, the process proceeds to S5 to start an automatic return timer built in the microcomputer. Next, in S6, the microcomputer determines whether or not the automatic return timer has finished counting (that is, whether or not a predetermined time has elapsed after returning to the close position). If YES, the process proceeds to S7.
In S7, the microcomputer performs open control of the panel mechanism 3 (to the last adjustment position P2). Then, in S8, the microcomputer determines whether or not the panel mechanism 3 has reached the last adjustment position. The driving means such as the motor is stopped, and the panel mechanism 3 is brake-controlled to stop. Then, the operation is terminated.
[0016]
As described above, even when the panel mechanism is at the adjustment position P2, it is possible to smoothly load the disk to the playback unit. In addition, the mechanism operates intelligently.
[0017]
【Example】
Although the embodiment of the present invention has been described with respect to an MD disk, the present invention is not limited to this, and it is possible to record / reproduce an audio source system such as a cassette tape or a video source system such as a video disk. The present invention is applicable to various recording medium reproducing devices.
[0018]
【The invention's effect】
According to the present invention, it is possible to smoothly load a recording medium regardless of whether the panel mechanism including the front panel and the recording medium insertion portion is in the non-adjustment position or the adjustment position.
