Title: Multipurpose media player memory card reader

Description:
BACKGROUND OF THE INVENTION  
      (a) Field of the Invention  
      The present invention relates to a multipurpose media player memory card reader.  
      System flow occurs upon inserting a memory card being inserted into a memory card reader slot, whereupon a circuit of the memory card reader reads data stored within the memory card or a control circuit reads data stored within memory, accordingly multimedia data is transmitted to a multimedia player circuit and converted into sound signals for output through an outlet thereof. When playing multimedia data the multipurpose media player memory card reader is further adapted to reciprocally connect to a computer port through a connector port of the multipurpose media player memory card reader, thereby the multipurpose media player memory card reader achieves functionality as a removable connected hard disk, whereby a user is able to save data within a memory card and memory through the multipurpose media player memory card reader.  
      (b) Description of the Prior Art  
      A conventional card reader includes only a function to read memory cards, and a general media player device, such as a MP3 personal stereo, includes only a function to play MP3 data, these devices do not include functionality to be utilized as a medium for saving data. A user is therefore obliged to purchase other equipment, thereby adding a burden the user.  
      Therefore, the present invention attempts to resolve the technical difficulties existence in eliminating the foregoing disadvantages.  
     SUMMARY OF THE INVENTION  
      Referring to  FIGS. 1 and 2 , which show a multipurpose media player memory card reader according to the present invention, and constructed to include a card reader A comprising an upper cover A 1 , a lower cover A 2 , and a circuit board B having main characteristics including the circuit board B laid between the upper cover A 1  and the lower cover A 2 , screws A 3  pass through screw holes A  21  of the lower cover A 21  and screw holes C 8  of the circuit board B, therewith fastening to a screw hole support of the upper cover A 1 .  
      The circuit board B is configured to include a card reader port C 1 , a control circuit C 2 , a card reader circuit C 3 , a multimedia player circuit C 4 , a battery C 5 , memory C 6 , memory card slots C 71 , C 72 , and C  73 , a socket C 9 , a wireless transmitter circuit C 10 , a transmitter C 11 , and an electric power socket C 12 .  
      Main characteristics of the present invention are such that upon a memory card D being inserted into a memory card slot C 71 , C 72 , or C 73 , a card circuit C 3  reads data within the memory card D or a control circuit C 2  reads data stored within memory C 6 . The control circuit C 2  differentiates whether or not the data is multimedia data. The multimedia data is transmitted to a multimedia player circuit C 4 , whereupon the multimedia data is converted to sound signals and output through an outlet C 9 . When playing multimedia data, the card reader port C 1  of the multipurpose media player memory card reader A is also adapted to mutually connect to a compute port E, thereby the multipurpose media player memory card reader A is enabled as a removable connected hard disk, wherewith a user can utilize the multipurpose media player memory card reader A to store data within the memory card D and memory C 6 .  
      Furthermore, in usage, the wireless transmitter circuit C 10  and the transmitter C 11  are configured to transmit multimedia data as wireless signals, whereupon multimedia equipment of a vehicle receiving the wireless signals can play the multimedia data thereof.  
      A battery C 5  provides electric power required when the control circuit C 2  and multimedia player circuit C 4  are in operation. Moreover, the card reader port C 1  and a computer port may be utilized to recharge the battery C 5 , thereby making it unnecessary to change the battery C 5 .  
      A transformer or vehicle usage plug can be connected to the electric power socket C 12 , and thereon connected to a power supply socket or a vehicle cigarette lighter socket, thereby saving power consumption of the battery C 5  while providing working electric power to the card reader A, and electric power to recharge the battery C 5 .  
      The card reader port C 1  may be made to connect to a computer port, whereby the card reader port C 1  can comprise a USB port (Universal Serial Bus), COM1/COM2 communication ports, PRINT PORT, and related ports utilized by electronic digital products.  
      The memory card slots C  71 , C 72  and C 73  are compatible with CF card (Compact Flash Card), MS card (Memory Stick Card), SM card (Smart Media Card), and related medium utilized to store electronic digital data.  
      The Memory C 6  can be RAM (Random Access Memory), DRAM (Dynamic Random Access Memory), SRAM (Static Random Access Memory)), SDRAM (Synchronous Dynamic Random Access Memory), FLASH, and related memory utilized by electronic digital products.  
      The wireless transmitter circuit C 10  and wireless signals of the transmitter C 11  are further configured to comply with AM (Amplitude Modulation) signals, FM (Frequency Modulation) signals, Bluetooth signals, IEEE 802, 11A, B (Institute of Electrical and Electronic Engineers 802, 11A, B), and related modulation carrier wave signals of wireless communication.  
      The Battery C 5  can employ carbon zinc battery, mercury battery, lithium battery, nickel-hydrogen battery, and related batteries employed in electrical digital products.  
      To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.
