Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a signal recording apparatus adapted to record a still picture in a first recording medium such as a video tape and in a second recording medium such as a semiconductor memory. 
     2. Description of Related Art 
     Many of the conventional signal recorders use only a single alarm or warning sound to inform the user of the operation and status of them. The single sound has only one tone in many cases. 
     As in the above, the apparatus is designed to provide an alarm or warning sound upon operation thereof However, if the apparatus provides different results from one operation, sound is used to inform the user of the operation. In this case, if only a single sound is available or if the sound has only a single tone, the user will not be able to know which one of the possible different results has been led from the operation of the apparatus. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of the present invention to overcome the above-mentioned drawbacks of the prior art by providing a signal recording apparatus and method adapted to produce different sounds which allow the user to correctly tell apparatus functions different from but similar to each other. 
     The above object can be attained by providing a signal recording apparatus comprising a first recording medium and second recording medium, to both of which a signal can be recorded, and a controlling means for providing a difference between a trigger sound issued when a still picture is recorded into the first recording medium and a one issued when a still picture is recorded into the second recording medium. 
     The signal recording apparatus is also adapted to record a moving picture in addition to a still picture into at least the first recording medium. 
     The controlling means generates a different trigger sound from a different source. Further, the trigger sound source for recording a still picture into the second recording medium is put in a sleep mode when it is unused. 
     These objects and other objects, features and advantages of the present intention will become more apparent from the following detailed description of the preferred embodiments of the present invention when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to FIG. 1, there is illustrated a signal recording apparatus according to the present invention. More specifically, it is a video camera/recorder, generally indicated with a reference numeral  1 . The video camera/recorder  1  is provided with a portable memory card, and incorporates a video tape  10  and a nonvolatile memory  13  as recording media. The video camera/recorder  1  is adapted to record a moving picture and still picture into the video tape  10  while recording a still picture into the nonvolatile memory  13 . 
     When the user selects a mode of still picture recording, the video camera/recorder  1  will generate one trigger sound for recording into the video tape  10  and another trigger sound destined for recording into the nonvolatile memory  13  and which is definitely different from the sound for recording into the video tape  10 . 
     As seen from FIG. 1, the video camera/recorder  1  comprises a camera  2 , operation keys  4 , and a microcomputer  5  which controls a select switch  3  to select recording into either the video tape  10  or into the nonvolatile memory  13  according to a selection made by the user operating the operation keys  4 . 
     Further, the video camera/recorder  1  comprises an image control circuit  8  which provides an image processing to be effected appropriately when the microcomputer  5  places the select switch  3  at a position for recording a still picture into the video tape  10 , and a magnetic head  9  to record an image signal from the image control circuit  8  into the video tape  10 . 
     Also, the video camera/recorder  1  comprises an image control microcomputer  11  which provides an image processing to be effected appropriately when the microcomputer  5  places the select switch  3  at a position for recording a still picture into the nonvolatile memory  13 . 
     The microcomputer  5  is connected thereto via a switch  6  a sound generator  7  which generates a pulse sound like “crackling” as a trigger sound when a still picture is recorded into the video tape  10 . The sound generator  7  generates the sound in the PWM (pulse width modulation) mode. 
     The image control microcomputer  11  is connected thereto a sound generator  12  which generates a shutter sound like “clicking” as a trigger sound when a still picture is recorded into the nonvolatile memory  13 . 
     The sound generator  12  is in the sleep mode when the microcomputer  5  is detecting a recording into the video tape  10 , namely, when the sound generator  12  is not in use. Therefore, the sound generator  12  will consume no extra power. 
     The video camera/recorder  1  functions as will be described below: 
     In the video camera/recorder  1 , the microcomputer  5  detects a function selected by the user operating the keys  4 , and selects any one of the recording media to which an input picture is to be recorded. When the video tape  10  is selected as a destination of this recording, a contact c of the switch  3  is connected to a terminal a and thus an picture picked up by a camera  2  is passed through the image control circuit  8  and recorded into the video tape  10  via the magnetic head  9 . At this time, the microcomputer  5  will turn on a switch  6  so that the sound generator  7  will generate a “crackling” alarm sound upon pressing, by the user, of a photo key included in the operation keys  4 . 
     When the user selects one of the operation keys  4  for recording into the nonvolatile memory  13 , the switch contact c of the switch  3  is connected to a terminal b and thus an picture picked up by the camera  2  is passed through the image control microcomputer  11  and recorded into the nonvolatile memory  13 . At this time, the microcomputer  5  will turn off the switch  6  and the sound generator  12  connected to the image control microcomputer  11  will generate a “clicking” sound upon pressing, by the user, of the photo key included in the operation keys  4 . 
     The video tape  10  can record a moving picture in addition to a still picture, but the nonvolatile memory  13  can record only a still picture. Since the video camera/recorder  1  operates similarly to a conventional still camera, so the operation alarm sound should desirably be similar to the operating sound of still camera. 
     In case one video camera/recorder  1  has similar functions as mentioned above, it is provided with the two sound generators  7  and  12  one of which is put into operation by the microcomputer  5  detecting which one of the functions has been selected, thereby providing an alarm sound for the selected function, which is discernible from a one for another selected function. 
     If it is allowed from the econoimcal aspect to use a microcomputer  5  having a relatively high capability of processing, the sound generator  12  may be connected to the image control microcomputer  11 . Further, only the sound generator  7  may be used to generate two alarm sounds without using the sound generator  12 . 
     When an apparatus having a single function is already available and a new apparatus which incorporates the existing apparatus is designed, a sound source which generates a sound similar to the alarm sound issued for the single function may be provided to allow the user to clearly understand the function incorporated in the new apparatus. 
     FIG. 2 shows a video camera/recorder I using a PC card as the second recording medium in place of the nonvolatile memory  13 . 
     The video camera/recorder  1  operates on a battery  21 . The PC card  23  is inserted into the vide camera/recorder  1  through a card slot  22  as shown in FIG.  3 . The PC card  23  can record a still picture picked up by the video camera/recorder  1  as in the above, and an picture already existent on the video tape  10  also set in the video camera/recorder  1 . The video tape  10  can also record a still picture and also a moving picture. 
     When the user selects to record a still picture into the PC card  23  and presses a photo button  24 , a “clicking” sound is generated from the sound generator  12  at the same time. Also, when the user selects to record a still picture into the video tape  10  and presses the photo button  24 , a “crackling” sound is generated from the sound generator  7  at the same time. 
     Thus, the user can be informed, by such different sounds, of which one of the functions is performed. 
     As having been described in the foregoing, the present invention permits to inform the user of which one of similar functions incorporated in one apparatus is performed.
