This process is started when the DAP is connected to the input terminal 3 of the playback apparatus after accepting the setting of the playback start position by the user and shifting to a predetermined standby state in response to the power-off operation by the user. The

  When the process is started, first, in step 301, the power-on and reproduction start instructions (steps 34 and 37 in FIG. 2) from the reproduction apparatus are waited. When the instruction is received, in step 302, the power is turned on to cancel the standby state. Further, in step 303, reproduction is started from the set reproduction start position, and the processing of FIG. The reproduction signal is supplied to the reproduction device via the input terminal 3 and is output as sound in the reproduction device.

  FIG. 4 is a flowchart showing another part of the operation in the DAP. This process is started when the DAP that is in the power-on state or is in the reproducing operation is connected to the input terminal 3 of the reproducing apparatus. When the processing is started, first, in step 41, the reproduction standby from the playback device or the power-off instruction (steps 28 and 29) is waited. When the instruction is received, in step 42, it is determined whether or not the reproduction operation is being performed. If the reproduction operation is not being performed, the process proceeds to step 44 as it is. The playback position is stored and the process proceeds to step 44.

  In step 44, the power is turned off to shift to a standby state, and in step 45, the power on and reproduction start instructions (steps 34 and 37) from the reproduction apparatus are waited. When the instruction is received, in step 46, the power is turned on to cancel the standby state. Further, when the playback position is stored at step 47 or when the playback position is stored at step 43, playback is started from the stored playback position. Thereafter, the process of FIG. 3 is terminated. The reproduction signal is supplied to the reproduction device via the input terminal 3 and is output as sound in the reproduction device.

  According to the present embodiment, when the DAP is connected in the timer standby mode, the reproduction is stopped if the DAP is being reproduced, and if the selector 6 is not set to select the DAP, the DAP is selected. When the set time of the playback start timer is reached, the DAP is instructed to start playback, so that timer playback using the DAP as a sound source can be easily performed. That is, timer playback can be performed from the music or from the playback position at that time simply by selecting the music in the DAP or starting playback of the music and connecting to the playback device in the timer standby mode state. Further, it is not necessary to set the playback apparatus to select a DAP from a plurality of sound sources, and the playback apparatus side can be set only by setting the playback start timer. In addition, the DAP is set to a standby state when the DAP is connected, and the DAP is set to a power-on state when timer reproduction is started. Therefore, power saving in the DAP can be achieved.

  Note that the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications. For example, in the above description, the selection target by the selector 6 is the CD mechanical unit 2, the input terminal 3 (DAP), and the input terminal 4, but the selection target is not limited to these. For example, an MD (mini disc) mechanical unit or a tuner may be included in the selection target.

  In the above description, the sound source to be played back by the timer when the DAP is not connected is a sound source that is set in advance so that the selector 6 selects it. In this case, priority is given to each sound source in advance. If the sound source selected by the selector 6 cannot be used, the sound source having the next highest priority may be used after that sound source.

  Further, in the above description, the sound source to be played back by the timer when the DAP is not connected is a sound source that is set in advance so that the selector 6 selects, but instead, the DAP is not connected. In this case, the sound source to be played back by the timer may be a sound source that can be used in accordance with a preset priority order. For example, if the DAP is not connected, the sound source selected by the selector 6 is the CD mechanical unit 2 if it is available, the MD mechanical unit if no CD is loaded, and the MD is not loaded. In some cases, a tuner may be used.

  Although not mentioned above, if the DAP connection is released after the DAP connection (step 22) and before the set time of the playback start timer arrives, the timer standby mode is canceled and the remote control is released. You may make it transfer to the normal standby mode which can accept the power-on instruction | indication by. When the timer standby mode is canceled, the set time of the playback start timer may be maintained or may be canceled. In the case of maintaining, the set time can be used when the transition to the timer standby mode is instructed again thereafter.

  In the above description, when the DAP connection is detected (step 22), the sound source selected by the selector 6 is unconditionally set to DAP. Instead, the sound source selected by the selector 6 is set to DAP. A user instruction may be accepted as to whether or not to set.

  Moreover, in the above, timer playback is performed in response to the arrival of the set time, but instead of this, the elapsed time since the timer playback was shifted to the timer playback mode, It may be performed in response to exceeding the set time.

  In the above description, when the DAP connection is detected before the set time of the playback start timer is reached, the DAP is instructed to start playback when the set time arrives. (Steps 33 and 36) In the case of setting the timer also in the DAP, this instruction may not be given.

  In the above description, the DAP is described as an example of an external device that is a sound source for timer playback when connected to a playback device. However, the external device is not limited to a DAP, and may be a tuner or the like. Good.
